Murray, Frazier and Holmes talked about the film at today’s Spike panel at the Television Critics Assn. gathering in Pasadena. Ali has evolved from controversial figure to folk hero in recent years, but the documentary’s principals feel all sides of him still need to be remembered.

“He said a lot of things to me, he said a lot of things about Joe,” Holmes said. “We didn’t appreciate it. We were there to fight and to win – try not to get hurt.

“But Ali’s a very important part in our lives, because without him, boxing probably would not be alive.”
